Scanning power view of lichen nitidus identifies a focaldermalinflammatoryinfiltrate enclosed within collarettes of epidermalacanthosis (Figures 1 and 2). Focalerosion of the epidermis in figure 1 indicates excoriation. Higher power view identifies a well circumscribed lymphohistiocytic infiltrate with multinucleatedgiant cells (Figures 3 and 4).
